	==Wordlists==		==Wordlists==

	* [[bip-0039/bip-0039-wordlists.md\|~~Moved to separate document~~]]		Since the vast majority of BIP39 wallets supports only the English wordlist,
			it is '''strongly discouraged''' to use non-English wordlists for generating
			the mnemonic sentences.

			If you still feel your application really needs to use a localized wordlist,
			use one of the following instead of inventing your own.
